    Routing 650sx for rear exhaust

    I have a project that I am working to put together. I recently learned that someone converted it to rear exhaust on the right side.

    I thought it was factory but found it was too old and route s out the wrong side.

    I removed the gas tank and found there was no water box.

    The exhaust hose wraps around the front of the ski with a couple of elbows.

    Is this how the mod is supposed to work? It seems to me that it will be pretty loud. Is there a box that I can swap in?

    Depending on the hose size that was used either a 550 waterbox or a Superjet waterbox would work. mine is set up pretty much the same as yours but I installed two resonators inline to dampen the noise so that is also an option
    Y'all know me, still the same O.G. but I been low-key
    hated on by most these &^$$@s with no cheese, no deals and no G's, no wheels and no keys, no boats, no snowmobiles, and no skis, mad at me cause I can finally afford to provide my family with groceries

    I was 300SXing when 300SXing wasn't cool !

    If you decide to go the resonator route, I have two that could work as a possible solution.
    Never argue with an idiot, they will drag you down to their level then beat you with experience.

    Search out Gordy on ebay @ Pacific Jetsports. He has some modified 650 waterboxes modded for rear exhaust.

    I am going to be doing this on my 650sx in the next few months. I am just going with the same routing with the exhaust coming out the left side instead of the right.

    I also have a aftermarket 650 waterbox for sale if anyone has interest or is in need.
